This paper designed a kind of broad band voltage transformer measurement system suitable for train sets tracking motors, whose iron core adopted nano-crystalline alloy material. The secondary side outlet voltage of the measurement system was smaller. The converted output voltage was sampled by single chip. Proteus simulation platform was used to finish initial test for voltage signal and frequency signal. Simulation result shows that the system can complete test for voltage and frequency, realizing broad band measurement and making up insufficiency of traditional voltage transformer, with reasonable software and hardware disposition, short development cycle, simple structure and high sampling accuracy etc advantages.
